How to replace plain URLs with links?

So I’ve got a page with a bunch of URLs and no links. The page is constantly pulling in new information, so I can’t add the tags myself. Where could I find a fast, lightweight, JavaScript snippet or jQuery plugin to linkify these URLs?

Turn http://blahblah.com/

into <a href="http://blahblah.com/">http://blahblah.com/</a>

With JQuery:
Assuming your links are in p (for performance, use the closest selector)

$(document).ready(function(){
    $('p').each(function(){
        var content = $(this).html();
        content = content.replace(/[^"=](http:\/\/\S*)/ig, '<a href="$1">$1</a>');
        $(this).html(content);
    });
});​

Surely not the most optimized way, and the regex is not really well-formed but at least it doesn’t replaces URLs that are in tags attributes (like images src).
